I spent over an hour this morning trying to find a decent title for this post. I even used an anagram generator, but some of the words were far from flattering. So I decided to use the proper title for the ship I saw and posted yesterday.
I did a search this morning for “Oil rig legs on a ship” then “On a vessel” and found a Jack Up Rig. It appears that this vessel is a Jack Up Rig. A ship that lowers its legs to the sea bed and then lifts the main vessel up above sea level. Because of what it is, it cannot go on its own. There is no propulsion so it needs another ship to pull it.
You can see the large ship in front that is pulling the rig.
